Reviving a vintage Centropen 32 (301) fountain pen from the 80's Czechoslovakia and a sample writing

Here I'm trying to revive a Centropen 32 or 301 fountain pen made in Czechoslovakia in the end of the 1980s. I got 2 of these from my aunt when she left (back then) the Polish People's Republic for Austria and she might have gotten this pen on her way through nowadays Czechia/Czech Republic where Centropen company has been based for many decades now. This fountain pen is entirely made of plastic and the nib is metal. It's painted gold and feels light in the hand. There's a piston only instead of any converters or ink cartridges.
